Application filed June 25, 1900. Serial No. 21,453- (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM W. DINGEE, a resident of the city and countyof Racine, in the State of Wisconsin, have invented certain new anduseful Improvements in W'ind- Stackers, of which the followin g is afull, clear, and exact description.

The invention relates to fan-blast stackers now frequently used inconjunction with to threshing-m aehines to remove the loose straw, chad,etc. from the interior of the thresher by the aid of an air-blast andthence to elevate and project such refuse materials onto an adjacentstack or heap.

The nature of the improvements will appear in detail from thedescription following and be thereafterpointed out by claims at theconclusion.

On the drawings, Figure 1 is a side elevation toward the rear of thethresher, showing the stacker attached 5 Fig. 2, adetail sectional viewat the junction of the main trunk with the turret of the straw-pipe;Fig. 2, an enlarged sectional view at the joint of the turret with itsplatform -ring; Fig. 2", a plan view of said ring, the turret beingremoved; Figs. 3 and32respectively, plan and elevation views of thetrunk part of the straw-pipe; Fig. 4:, a plan view of the fan with thetop of its case taken off; Fig. 4;, a transverse sectional View of thefan and case; Fig. r, a development of the curved sheet constituting afan-vane; Figwlfian enlarged sectional View of the fan-axle and itsbox-bearing; Fig. 4, a

35 transverse sectional view of the fan and case at right angles to Fig.at.

The threshing-machine, with its usual casing, is carried on thecustomary running-gear,

the casing Ct for the stacker being attached 4.0 at the rear incontinuation of the main frame, but with its sills set at a slightincline, as shown, Fig. 1. Brackets a, fastened on each side beneath thesills, carry the cross-trees a upon which rests the fan-case A, Fig. t,the

5 angular wings for journal-box a being snugly secured at confrontinglower edges of the cross trees a to constitute a stout interbrace.Fan-axle 1 extends through the elongated journahhox a and at its lowerend is stepped on an antifriction -bearing with a seat therefor interminal cup 2. The cup is divided longitudinally, its two halves beingclamped to position about the journal-box by means of the confrontingears 2 and the screw-bolts therefor. Stepbolt 3 projects through the cupto adjust the antifrictionbearing, while collar 4:, clamped to the axlewithin cup 2, affords seat for a series of balls in touch with the loweredge of journal-box a It is seen that axle 1 may easily turn, but isheld from all endwise shift either up or down. \Vhen in rapid motion,the fan tends to lift the axle, together with collar 4, so that theballs thereon travel against the lower edge of box a Above thejournal-box the head of fan-axle 1 socketsin the eye of miter gear-wheel5, which latter is driven by companion gear 5, carried on shaft 5 Theshaft is sustained in bearings from the cross-ties a and is rotated bypulley 5 from any suitable source of power.

Bolted upon or cast in piece with gear- Wheel 5 is the fan-hub 6,carrying spokes 7, projected therefrom in offset instead of usual radialrelation. The spokes sustain the sev- 5 eral disk-sections, whichtogether constitute the fan proper. Fan-hub 6 being in fact or effect anintegral part of gear-Wheel 5, it is seen that the fan freely rotatesunder direct control of the gear 5 5. Axle l manifestly serves as acentering-stud rather than as a medium for communicating the power,although in ordinary practice it is customary to unite the axle with thehub by the aid of pinch-screw or other expedient. Should the screwloosen while the machine-is running, the fan still persists in itsmotion, owing to the control relation of the gear 5 5.

The disk-sections 8 to constitute the fan are conveniently cut in thegeneral form shown, Fig. a, and are united at their bentup edges to thesides of the spokes, one free edge curving over to constitute the vaneor wing.

The presence of the disk as part of the fan 5 relieves the load fromfriction contact with the casing, and besides enables the load toacquire an initial impetus for its ascent,while the offset position ofthe vanes causes the air to draw evenly into all parts of the fan-eye,I00

and thus enables the burden to be steadily projected and elevatedthrough the casingoutlet. 7

Upon the operators platform or deck at the rear is fastened the circulartable 10, having "circular parts furnished with a grooved upperextension or lip to afford seat for the series of antifriction-ballslocated between said lip and the turret-ring 13. The ring is sleeved bya vertical joint within the table 10 and through the medium of theinterposed ball-bearings is not only free to rotate back and forth, butunder coaction with the table is kept upright to prevent any sagging ofthe main trunk of the conduit. Thus constructed there is no need for thehasps or overhangs which are generally present to hold the turret-ringin place when a simple horizontal joint is employed between the ring andtable, as in prior machines. Hasps or overhangs often interfere with theeasy play of the toothed drive-flange carried on the turretring.

Drive-flange 14 is here shown projecting in piece from ring 13 above andover the upright lip of table 10. At the junction of the flange and ringis seated the angle-plate 16, carrying parallel radius-arms 15, which atpivot 18 unite with companion radius-arms 17,'having the usual collar toencircle the rear section of the main trunk.

Brace-standards 19, secured below against ring 13, afford journal-seatsat their apexes for the terminals of a cross-block 20, smoothlyreceiving the threaded rod 21., operated by hand-wheel 22. At itsforward end said rod engages a screw-nut 23, which journals betweenupright posts 24, projecting .from the ring for radius-arm 17. Onturning the handwheel the screw-rod 21 coacts with nut 23 to raise orlower the front of the main trunk about pivot 18 as a center.

Between lugs or ears 25, at the feet of upright posts 24, is fastenedthe rear end of a stifl" bar 26, extending thence over and parallel withthe trunk nearly to the outer joint of its telescopic sections. Anendless chain 50 passes around sprocket 27, carried at the front of bar26, and is secured by one of its links, as at 28, to the body of thetrunk. Sprocket 29, journaled in lugs 25, sustains the rear of the chainand by means of its hand-wheel enables the trunk-sections to be drawn inor out, as desired. When this occurs, the length of the straw-pipenecessarily varies; but this in turn renders some provision requisitefor ready adaptation of the swiveling discharge-nozzle and hood carriedthereby at the front of the trunk, so that these may conform to thetelescopic shift without breakage of the control-ropes or other parts.One of the upright posts 24 sustains an adjustable slotted plate 30,carrying a sheave 31, over which runs the rope 32, fastened forward tothe collapsible hood 33 and at the rear to one of the upper links, as at50 on endless chain 50. The movement of the link is exactly the reverseof the movement of the trunk-section which sustains the hood. Hence theplay of one precisely compensates for the play of the other, and thusthe hood remains at set position, unaffected by the telescopic shift. Insimilar fashion the oscillating tiller 34, pivoted at top of uprightpost 24 and secured by thumb-nut or like expedient, as desired, isfurnished with sheaves 35, over which run the reversing-ropes 36 for theswiveling nozzle. One end of each rope may be fixed to an upper chainlink, as at 50, after the manner of the hood-rope, while the oppositeends run past guide-sheaves 37 toward the front and on making ahalf-turn about the trunk hitch to the cowl-piece.

Obviously details of structure can be varied by the mechanics skillwithout departing from the essentials of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In wind stackers, the combination with the fan-casing and theelongated journal-box, of the fan-axle stepped in said box, thegearwheel sustained about the axle and carrying the fan-hub thereon, theseries of spokes projected from the hub, and the disk-sections withtheir edge vanes or Wings, said sections being fastened to the ontreaching spokes, substan tially as described.
